Nowadays, the Internet is becoming more and more important in our daily life. More than one billion Chinese people use the Internet every day. It brings us a lot of convenience and makes our life much easier and more colorful. We can do almost everything online. For middle school students, the Internet is a good helper for study. We can search for useful information, take online courses, read news from safe websites and learn new skills every day. It helps us open our eyes and know more about the world.

However, the Internet also has its disadvantages and risks. If we use it in a wrong way, it will be bad for us. Some students spend too much time playing online games, watching videos or chatting on social media. Too much screen time is harmful to their eyes, health and schoolwork. They may feel tired easily and can’t listen to teachers carefully in class. What’s worse, some bad

people use the Internet to do bad things. They may steal our personal information, send harmful messages or do online bullying. Some students even meet strangers online without telling their parents, which is very dangerous.

So it is important for us to use the Internet wisely and properly. We should make a clear daily plan for our online time and follow it strictly. We must protect our personal information and never share our password, address, phone number or ID number with strangers online. Before we click a link, we should double-check it to make sure it is safe. If we get bad or unfriendly messages, we should not reply. We can take a picture as a record and tell our parents or teachers at once.

The Internet is a wonderful tool. It is not good or bad itself. It depends on how we use it. If we use it correctly, it can help us a lot. If we misuse it, we will get into trouble. Let’s learn to control ourselves and make good use of the Internet.

We can keep in touch with each other easily no matter where we are. Secondly, mobile payment is very popular. We can buy things, pay bills and book tickets without cash, which saves a lot of time. Thirdly, we can use mobile phones to search for information, listen to English, watch educational videos and learn new things anytime and anywhere.
